Abstract

This study aims to describe the critical thinking skills of class VIII B students at a private junior high school in Jember Regency. This type of research uses descriptive qualitative. Data collection techniques used questionnaires, written tests, and interviews. The subjects used by the researchers were class VIII B at a private junior high school in Jember Regency. Subject data obtained 3 self-concept classifications including high self-concept, moderate self-concept, and low self-concept. Based on the three self-concept classifications, students' critical thinking skills are then analyzed in 4 indicators, namely interpretation, analysis, evaluation, and inference. The results of the study show that students' critical thinking skills in each self-concept have different classifications. Students with high (positive) self-concept have high (critical) critical thinking skills, students with moderate self-concept have moderate (sufficient) critical thinking skills, while students with low (negative) self-concept have critical thinking skills with low (lack) in problem-solving.

Abstract

Critical thinking ability is one of the higher orders thinking skills that is highly needed in 21st-century learning. One learning model that can develop and enhance students' necessary thinking skills, especially in learning mathematics, is the Discovery Learning model. Using video media in learning can motivate and assist students in learning mathematics. This study aimed to determine the increase in students' mathematical critical thinking skills through the Discovery Learning model helped by teaching videos. The research method used is quasi-experimental. The samples in this study were students at class VII Bandung National Middle School. The sample was selected by purposive sampling technique. This research shows that students who get the Discovery Learning model assisted by video-assisted learning have a higher mathematical critical thinking ability than those who get conventional models.

Abstract

Errors in associating some knowledge result in students' mistakes in choosing strategies so that problems cannot be solved. In fact, the new curriculum in Indonesia requires students to be able to solve problems that require higher-order thinking skills. This study aims to describe how students process problems in solving bridge context problems. This research is qualitative research with case study method. This research was conducted in April 2022 with the research subject being a junior high school student in Yogyakarta, Indonesia. The instrument in this research is the problem of high order thinking (HOT) to measure problem solving ability. The instrument was designed based on the mathematics material that students had learned and compiled through five times Focus Group Discussion (FGD) by 3 mathematics lecturers. Data were collected using documentation and interviews then will be analyzed descriptively. Based on the results and discussion presented in the previous section, the authors collect three types of errors in solving problems made by students. The three types of errors are operational, conceptual, and principal errors.

Abstract

Achieving the learning outcomes set for the classroom is the main goal of instruction. Todays’ teachers utilize various methods to achieve optimum learning for the students.  This study investigated the effect of peer tutoring strategy on the students’ achievement in solving exponential expressions. It also determined the students’ persistent errors in solving given exponential expressions. This study employed a quasi-experimental design and two intact classes randomly assigned to an experimental and control group. A validated 10-item test (α=.75) was utilized as the main instrument. Results revealed that students in the peer tutoring group performed better than in the lecture group. Moreover, the peer tutoring strategy significantly improved the learning outcomes of students in the experimental group. It is recommended that peer tutoring strategy may be used by mathematics teachers to improve their students' performance in the subject matter. Implications address the need to explore other teaching strategies suited for students in the Mathematics classroom.

Abstract

Mathematical problem-solving proficiency is one of the proficiencies that students must have to learn mathematics. The emotional quotient is one of the variables that influence pupils' capacity students mathematical problem-solving proficiency. Many research publications show that emotional quotient is closely related to students' mathematical problem-solving proficiency. This study aims to prove and validate the correlation between emotional quotient and students' Mathematical problem-solving proficiency. The data was obtained from a search on the Google Scholar database from 2013 to 2021. 23 research publications in Indonesia and Nigeria that met the criteria required as samples. Data analysis used a quantitative meta-analysis approach with a correlation meta-analysis. The findings reveal a positive and substantial correlation (5% significance level) between students' emotional quotient and students’ mathematical problem-solving proficiency. The mean effect size is 0.761 (high category) in the range of 0.578 and 0.944. This result demonstrates the coherence of the findings of the examined studies.

Abstract

Learning mathematics that emphasizes understanding concepts and solving problems requires learning media. The use of learning media is still low, so learning outcomes are far from the minimum completeness criteria (the student's lowest score), apart from learning media. Besides the media, learning models are essential to discover fun and not dull mathematics. This study aimed to improve learning achievement in data-building material through tangram media with the PjBL model for class IV at SD Negeri Gerih 7, East Java, Indonesia. The research method used was Collaborative Classroom Action Research. The subjects of this study were 23 students in grade IV at SD Negeri Gerih 7, East Java, Indonesia, in the 2022/2023 academic year. The test results obtained were in the form of pre-cycle class average values of 59.13, 64.78 in the results of the first cycle, and 77.82 in the results of the second cycle. It can be concluded that the PjBL learning model and the tangram media effectively improve the achievement results of fourth-grade students at SD Negeri Gerih 7, East Java, Indonesia.

Abstract

This study aims to analyze the literature review based on the analytic database on google scholar about mathematical reasoning related to gender. A total of 200 papers on mathematical reasoning were published in the harzing data base from 1959 to 2021 and analyzed through a bibliometric analysis approach. Aggregation of bibliographies from sources, authors, countries, institutions, publications and co-occurrence of authors' keywords were analyzed and visualized through VOSViewer software. Mathematical reasoning is heavily influenced by other things, one of which is related to gender differences in it. The results from the bibliometric data of the Harzing Application and VOSViewer that there is a distribution related to mathematical reasoning is very closely related to the key words difference, mathematical reasoning ability, reasoning, reasoning ability, mathematical ability, boy, girl, female, and male. The journal that has a lot of research on mathematical reasoning based on gender is the Journal of Educational Psychology, an institution that researches a lot on mathematical reasoning based on gender is the American Psychological Association. And the country that has researched the most on mathematical reasoning is the United States.
